media: pxa_camera: ignore -ENOIOCTLCMD from v4l2_subdev_call for s_power
When the subdevice doesn't provide s_power core ops callback, the
v4l2_subdev_call for s_power returns -ENOIOCTLCMD. If the subdevice
doesn't have the special handling for its power saving mode, the s_power
isn't required. So -ENOIOCTLCMD from the v4l2_subdev_call should be
ignored.
Actually the -ENOIOCTLCMD is ignored in this driver's suspend/resume,
but the others treat the -ENOIOCTLCMD as an error.
This prepares a wrapper function to ignore -ENOIOCTLCMD and replaces
all s_power calls with it.
This also adds warning message when s_power() is failed.
